Transformação de cicloexano e metilcicloexano sobre as zeólitas HMCM-22, HZSM-5 e HUSY rendimento e seletividade a hidrocarbonetos leves 

Scherer, Ediane Karine (Universidade Federal de São Carlos, 2009-03-27)
In Brazil, the oil production with high naphthenic hydrocarbon (HC) content and the hard growing for the petrochemical market have led to the necessity to maximize the production of light HC (in special light olefins). The ...

Catalisadores Cu-, Co- ou Fe-ZSM-5 caracterização e avaliação na redução de NO a N2 com hidrocarbonetos na presença ou ausência de vapor de água. 

Fernandes, Juliana Esteves (Universidade Federal de São Carlos, 2005-03-04)
The minimization of the emissions of nitrogen oxides (NOx) in the atmosphere has been one of the great goals in the area of environmental protection. Among the possible processes to treat the NOx, the selective catalytic ...

Formação de mesoporos na síntese de zeólitas ZSM-5 via nanomoldagem avaliação no craqueamento de n-decano 

Silva, Camila Ramos da (Universidade Federal de São Carlos, 2008-04-04)
The use of zeolites in the cracking of hydrocarbons is limited because the molecules higher than 0.74 nm do not diffuse in their micropores. In the other hand, molecular sieves as MCM-41, MCM-48 ou SBA-15, whose diameters ...

Seletividade da Clinoptilolita natural por metais tóxicos em sistemas aquosos. 

Fernández, Juan Carlos Torres (Universidade Federal de São Carlos, 2004-12-13)
Natural zeolites are the most important inorganic cationic exchangers exhibiting high ion exchange capacity, selectivity and environment compatibility. Heavy metals are well known for toxicity and their disposal is a ...

Catalisadores à base de Mo, NiMo e CoMo suportados sobre y-Alumina ou Al-MCM-41 - Avaliação na hidrodessulfurização do dibenzotiofeno 

Baston, Eduardo Prado (Universidade Federal de São Carlos, 2007-04-13)
The effect of the γ Al2O3 synthesized by Sol-Gel method and Al-MCM-41 mesoporous molecular sieves used as supports in the preparation of Mo, NiMo and CoMo catalysts was studied. The activity and selectivity of the ...

Filtração de gases: estudo da deposição de diferentes tortas de filtração em diferentes meios filtrantes 

Rodrigues, Karina Bassan (Universidade Federal de São Carlos, 2006-06-19)
The particle retention inside a filter medium, after cleaning, significantly improves the initial pressure drop during the subsequent cycle, that is, the residual pressure drop. However, the way as these particles ...

Estudo do mecanismo eletroforético de coleta na filtração de aerossóis 

Mello, Rafael Lopes Seabra de (Universidade Federal de São Carlos, 2007-05-18)
Previous works have shown that the presence of electrostatic forces in particles significantly affect the performance of a filter, both increasing collection efficiency and reducing pressure drop. Recently, in the Environmental ...

Desempenho de filtros fibrosos operando na remoção de partículas nanométricas de aerossóis 

Steffens, Juliana (Universidade Federal de São Carlos, 2007-02-28)
The increase in the air pollution in the last decades is causing a strong increase in the monitoring and control of emissions of particulate matter in the atmosphere, in order to minimize the problems caused to the ...

Secagem de pêra em secador a microondas 

Fumagalli, Fabíola (Universidade Federal de São Carlos, 2003-08-05)
The present work has as main objective the pear drying in three different dryers: convective, microwave and microwave-convective. It is also intended to evaluate the effect of the osmotic dehydration, as pré-treatment, in ...

Estudo da fluidodinâmica em leito fixo utilizando-se métodos numéricos de solução: escoamento monofásico de ar 

Béttega, Rodrigo (Universidade Federal de São Carlos, 2006-03-09)
Studies accomplished in the structure of tubular fixed beds proved that the porosity in these systems presents an oscillatory behavior along the radial direction. The non-uniformity of the porosity generates a behavior of ...
